The slope equations: A universal relationship between local structure and glass transition temperature
نویسنده
چکیده
In this article, we present a universal relationship between the glass transition temperature Tg and the local glass structure. The derivation of the simplest expression of this relationship and some comparisons with experimental Tg values have already been reported in a recent letter. We give here the analytical expression of the parameter β of the Gibbs-Di Marzio equation and also new experimental probes for the validity of the relationship, especially in low modified binary glasses. The influence of medium range order is presented and the unusual behavior of Tg in binary B2S3 and P2S5 systems explained by the presence of modifier-rich clusters (denoted by B−B doublets).

Modification of Polyaniline/Polystyrene and Polyaniline/Metal Oxide Structure by Surfactant
Polyaniline/polystyrene (PAni/PS) composites were prepared in aqueous solution by polymerization of styrene and aniline in two-stages. Firstly styrene polymerize by using Ammonium persulfate (APS) as an oxidant in the presence of various surfactants such as poly(vinyl pyrrolidone) (PVP), hydroxypropylcellulose (HPC), poly(vinyl alcohol) (PVA) and surfactive dopant sodium dodecylbenzenesulfonate...
متن کاملA universal description of ultraslow glass dynamics
The dynamics of glass is of importance in materials science but its nature has not yet been fully understood. Here we report that a verification of the temperature dependencies of the primary relaxation time or viscosity in the ultraslowing/ultraviscous domain of glass-forming systems can be carried out via the analysis of the inverse of the Dyre-Olsen temperature index. The subsequent analysis...
متن کاملWeak correlations between local density and dynamics near the glass transition.
We perform experiments on two different dense colloidal suspensions with confocal microscopy to probe the relationship between local structure and dynamics near the glass transition. We calculate the Voronoi volume for our particles and show that this quantity is not a universal probe of glassy structure for all colloidal suspensions. We correlate the Voronoi volume to displacement and find tha...
متن کاملA relationship between diffusivity and cooperativity of supercooled liquids in the proximity of glass transition
In structurally disordered glass-forming liquids, the Stokes-Einstein (SE) law for translational diffusivity is violated, in particular, in the proximity of the glass transition temperature. Usually, the violation of the SE law is explained as due to the decoupling of the diffusivity from the viscous flow. Meanwhile, one of the prominent features observed in the supercooled liquids is the drast...
